technical field

The present application relates to a transmission method and device in a wireless communication system, in particular to network optimization of wireless communication, multiple TRP communications, and methods and devices related to layer 1 and layer 2 mobility and related signaling.

Background technique

The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) (or Fifth Generation, 5G) to conduct research, passed NR's WI (Work Item, work item) at the 3GPP RAN#75 plenary meeting, and started to standardize NR.

In communication, whether it is LTE (Long Term Evolution, long-term evolution) or 5G NR, it will involve accurate reception of reliable information, optimized energy efficiency ratio, determination of information validity, flexible resource allocation, and scalable system structure. Efficient non-access layer information processing, low service interruption and drop rate, support for low power consumption, which is important for normal communication between base stations and user equipment, reasonable scheduling of resources, and balance of system load Meaning, it can be said to be the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality, whether it is eMBB (ehanced Mobile BroadBand, enhanced mobile broadband), URLLC (Ultra Reliable Low Latency Communication, Ultra-reliable and low-latency communication) or eMTC (enhanced Machine Type Communication, enhanced machine type communication) are indispensable. At the same time, in IIoT (Industrial Internet of Things, the Internet of Things in the industrial field, in V2X (Vehicular to X, vehicle communication), in the communication between devices (Device to Device), in the communication of unlicensed spectrum, in User communication quality monitoring, network planning optimization, in NTN (Non Territerial Network, non-terrestrial network communication), in TN (Territerial Network, terrestrial network communication), in dual connectivity (Dual connectivity) system, in wireless resource management As well as multi-antenna codebook selection, there are extensive requirements in signaling design, neighbor cell management, service management, and beamforming. Information transmission methods are divided into broadcast and unicast, both of which are 5G Systems are essential because they are very helpful in meeting the above requirements. The UE can connect to the network either directly or through a relay.

As the scenarios and complexity of the system continue to increase, higher requirements are put forward for reducing interruption rate, reducing delay, enhancing reliability, enhancing system stability, business flexibility, and power saving. Compatibility between different versions of different systems also needs to be considered during system design.

Contents of the invention

In a variety of communication scenarios, the use of multiple antennas will be involved, such as using MIMO technology, for example, through multiple transmission points (multi-TRP, multi-TRP/M-TRP, multiple transmission points or multiple transmission and reception points) to A user sends a message. Using multiple TRPs may help improve throughput and coverage in different situations. In order to further improve the performance, the multiple TRPs included in the multi-TRP may come from the same cell identified by one physical cell identity, or different cells identified by different physical cells. In earlier versions of 5G NR, a serving cell and a physical cell identity usually have a definite relationship. It is generally believed that a serving cell includes only one physical cell identity, and a physical cell identity belongs to only one serving cell. Therefore, problems arise when TRPs from cells identified by different physical cell identities are configured to users through one cell, a feature that many aspects of the current 5G system cannot support. On the other hand, when the user detects beam failure and triggers beam failure recovery, it needs to indicate relevant information to the network, for example, indicate beam failure recovery information. This will encounter some difficulties, including how to use fewer bits to report beam failure recovery information, how to report beam failure recovery information of multiple cells at the same time, how to use the relatively fixed signaling format of MAC CE to report, how to Report beam failure recovery information as much as possible for different uplink resources, and how to maintain a certain compatibility with the existing protocol architecture.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. The L1 layer will be referred to herein as PHY 301 . Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the first node and the second node and the two UEs through the PHY 301 .
